3 Claims.

This invention relates to flush tank valves used in connection with the flush tanks of toilets, the primary object of the invention being to provide means whereby the usual float valve will be guided in its movements to its seat, thereby insuring a true seating of the valve at all times.

Another object of the invention is to provide an attachment of this character which may be readily and easily positioned within a flush tank, eliminating the necessity of making alterations in the usual flush tank valve structure, to position the device.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure l is a side elevational view of an attachment, constructed in accordance with the invention, the float valve of the flush tank, being shown in dotted lines, as in an elevated position.

Figure 2 is a longitudinal sectional view through the valve seat and attachment, forming the subject matter of the present invention.

Figure 3 is a transverse sectional View taken on line 3-3 of Figure 2.

Figure 4 is a side elevational View of a modifled form of guide, illustrating the guide for the float valve, as secured in position over the valve seat.

Figure 5 is a perspective view illustrating the modified form of valve guide and housing.

Referring to the drawings in detail, the reference character 5 designates the usual outlet valve opening of a flush tank, which is formed with the usual valve seat 6, against which the ball or float valve l seats, in checking the flow of Water through the outlet opening.

The reference character 8 designates the usual overflow pipe which is secured to the body portion of the valve, to carry off the overflow from the flush tank, in which the valve is positioned. This overflow pipe 8 provides the support for the arm 9 that has openings at its free end, for the reception of the valve rod IE, to the lower end of which the ball or float valve 1, is secured in the usual and well known manner.

The guide, forming the subject matter of the present invention, is in the form of a cage indicated generally by the reference character l l, the upper end of the cage being flared as at I2, so that the ball or float valve 7, will be guided to the cage, as it descends with the water level within the tank. 5 V

This guide or cage H, has its lower end positioned over the annular rib I3 of the valve body, whereby the lower end of the cage is held against lateral movement. The reference character I l designates a band which encircles the cage, at a 10 point directly under the flared portion l2 thereof, the band being formed with an extension l5 provided with an elongated opening it.

The sectional clamp I1 is provided with screws that are disposed within the elongated opening i 6, so that the band may be adjusted or moved to a position directly over the outlet opening 5 of the valve body. The sectional clamp, is held in position on the overflow pipe 8, by means of the bolt I8 that passes through openings formed in. the ears IQ of the sectional clamp.

In the form of the invention illustrated by Figures 4 and 5 of the drawings, the guide is of a length to prevent the ball or float valve 26 from being extended beyond the upper end of the guide 5 or cage. The guide or cage is indicated by the reference character 2 l and is secured to the overflow pipe 22, by means of the clamp 23. The reference character 24 designates a cap which is formed with a plurality of bayonet slots 25 that cooperate with the pins 26, extending from the guide or cage 2|, in securing the cap 24 in position.

Extending upwardly from the cap 24, is a guide tube 27 through which the valve rod 28 extends, the valve rod being secured within the ball or float Valve 20.

From the foregoing it will be obvious that due to the construction shown and described, the ball or float valve of a flush tank, will be guided in its vertical movements, to the end that a true seating of the ball or float ,valve, will be insured at all times.

Having thus described the invention, what is claimed is:

1. A flush tank valve comprising a ball valve including a rod, a seat for the ball valve, a housing extending above the valve seat, a cover for the housing and having an opening through which the rod extends, an annular flange depending from the cover and having bayonet slots, pins extending from the housing and adapted to extend into the bayonet slots removably securing the cover to the housing, and said housing adapt- 2. A fiush tank valve comprising a valve body 7 having a valve seat and having an overflow pipe 7 supported by the valve body, a ball ,valve adapted to move into the valve seat cutting off the flow of water through the valve body, a housing rising from the valve body and encasing the ball valve, a band positioned around the housing, and means 7 10 for adjustably connecting the band to the over- 7 flow pipe, whereby the housing may be adjusterd with respect to the valve seat.

' 3. A flush tank valve comprising a ball valve including a rod, a seat for the ball valve, a housing rising from the valve body and encasing the ball valve, a vertically adjustable band supported within the flush tank, said band embracing the housing near the upper end thereof securing the housing in an upright position, and means at the upper end of the housing for guiding the ball valve to its seat within the housing.
